Each of modules 64-67 may comprise one or more program modules (e.g., program module 42 of FIG. 1) executed by the user computer device 60. In embodiments, the obstruction detection module 64 is configured to detect an obstruction of content displayed on the touch screen 61. In aspects, the content determination module 65 is configured to determine obstructed content in one or more areas, and determine a display configuration for a portion of the obstructed content (i.e., all or some of the obstructed content). In aspects, the content determination module 65 determines a display configuration based on content display rules stored in a rules database 68. In embodiments, the perspective determination module 66 is configured to determine a facial direction of one or more users relative to the touch screen 61.

It should be understood that the quantity of devices and/or networks in the environment of FIG. 2 is not limited to what is shown in FIG. 2. In practice, the environment of FIG. 2 may include additional devices and/or networks; fewer devices and/or networks; different devices and/or networks; or differently arranged devices and/or networks.

FIG. 3 shows a flowchart of a method in accordance with aspects of the invention. Steps of the method of FIG. 3 may be performed in the environment illustrated in FIG. 2, and are described with reference to elements shown in FIG. 2.

In embodiments, at step 300, the user computer device 60 accesses content display rules regarding relevant content to be projected. In aspects, the content determination module 65 accesses the content display rules stored in the rules database 68 of the user computer device 60. In embodiments, the user computer device receives rules from a remote device (not shown), such as a third party service provider (e.g., support services for the wearable projectors 90, 91) or directly from a user through a user interface of the user computer device 60, and stores the rules in a rules database 68 of the user computer device 60. In aspects, the user computer device 60 presents display rule configuration options or queries to a user, and the user's selection of the option or answers to the query determine the content display rules. In other embodiments, the user computer device accesses content display rules in a remote database (not shown), such as a database of a third party service provider, via the network 55. The content display rules may include rules regarding the type or category of content to be projected by one or more of the wearable projector devices 90, 91. For example, it may not be necessary or desirable to project certain types of content, such as decorative borders or the like. In embodiments, the content display rules comprise rules to only project text-based content.

At step 301, the user computer device 60 pairs with at least one wearable projector device 90, 91. In embodiments, the communication module 67 of the user computer device 60 includes Bluetooth technology to pair with the communication module 95, 98 of one or more wearable projector devices 90, 91. In aspects, the user computer device 60 pairs with the wearable projector device 90 of a first user and the wearable projector device 91 of a second user. Conventional pairing techniques may be utilized in conjunction with step 301.

Optionally, at step 302, the user computer device 60 pairs with one or more remote secondary cameras 92. In embodiments, the communication module 67 of the user computer device 60 includes Bluetooth technology to pair with the one or more secondary cameras 92. The one or more secondary cameras 92 may be cameras on other personal devices of the user (smartphone, smartglasses, laptop camera, etc.). Conventional pairing techniques may be utilized in conjunction with step 302.

At step 303, the user computer device 60 displays content on the touch screen 61. It should be understood that the type and amount of content displayed by the user computer device 60 is not intended to be limited by the present invention. Content may include, for example, text, images, diagrams, symbols, etc. Conventional display techniques may be utilized in conjunction with step 303.

At step 304, the user computer device 60 detects an obstruction of content in one or more areas of the touch screen 61. As used herein, the term obstruction of content means that an obstructing object (e.g., finger, stylus, etc.) is between the touch screen 61 on which content is displayed, and one or more users viewing the content, such that a portion of the content is obstructed from the view of the one or more users. Situations in which a user's interactions with touch screen 61 may create an obstacle to viewing content may include: typing text on the touch screen 61 with a finger/stylus, entering numbers on the touch screen 61 with a finger/stylus, selecting menus with a finger/stylus, or navigating content with a finger/stylus. In embodiments, or more of a plurality of different detection methods are utilized alone or in combination in performing step 304. For example, the user computer device 60 may utilize sensor data received from one or more proximity sensors 62, one or more remote secondary cameras 92, a camera 63 of the user computer device 60, and/or a camera (e.g., 94, 97) of a wearable projector device 90, 91 (e.g., smartglasses) to detect obstruction of the content on the touch screen 61. Other types of sensing devices such as strain gauges, light sensors or other conventional sensing technology (not shown) may be utilized in the performance of step 304. In one example, the obstruction detection module 64 of the user computer device 60 receives sensor data from the proximity sensors 62 and data from the camera 63 to determine that a user's view of content displayed on the touch screen 61 is being obstructed by the user's fingers as they use the touch screen 61. In another example, the obstruction detection module 64 of the user computer device 60 receives sensor data from the proximity sensors 62 and data from the camera 63 to determine that content displayed on the touch screen 61 is being obstructed by a first user's hand as the first user uses the touch screen 61, and simultaneously by a second user's hand as the second user touches the touch screen 61. The manner in which the user computer device 60 detects an obstruction of content on the touch screen 61 is not intended to be limited by the examples given herein.

At step 305, the user computer device 60 determines obstructed content in one or more areas of the touch screen 61 based on the obstruction of the content detected at step 304. In aspects, the obstruction detection module 64 sends data related to the detecting of an obstruction of content in one or more areas of the touch screen 61 (obstruction data) to the content determination module 65, and the content determination module 65 utilizes the obstruction data and data regarding which content is being displayed on the touch screen 61 to determine the amount and type of content that is being obstructed in real time. Various methods of comparing unobstructed content to obstructed content to determine the content that is to be projected may be utilized in conjunction with step 305. In one example, as a user's finger is moved across a touch screen 61 and obscures content on the touch screen 61, the content determination module 65 determines the content that is being obstructed in the particular area of the touch screen 61 obstructed, in real time, utilizing sensor data from the proximity sensors 62 in combination with data regarding the overall content being displayed. In this way, the user computer device 60 can determine the portion of the overall content being displayed that is being obstructed by the users finger. In another example, as both a first user's finger and a second user's finger are moved across different portions of the touch screen 61, the content determination module 65 determines the content that is being obstructed in multiple particular areas of the touch screen 61, in real time. Although discussed as two separate steps, it should be understood that steps 304 and 305 may be performed simultaneously or nearly simultaneously in real time by the user computer device 60.

In embodiments of the invention, at step 306, the user computer device 60 determines a facial direction of each of the one or more users relative to the touch screen 61. As used herein, the term facial direction means an angle at which a user is viewing the content (and any obstruction) on the touch screen 61, or an angle of the viewer with respect to the contact surface of the touch screen 61. In embodiments, the user computer device 60 determines the facial direction of each of the one or more users using data received from the camera 63 of the user computer device 60. For example, in the case where the user computer device 60 is a smartphone, the smartphone's camera 60 may capture image data, which the perspective determination module 66 of the user computer device 60 may utilize to determine the facial direction for each user with respect to the touch screen 61. In aspects, step 306 is performed upon detection of the obstruction of the content at step 304. In an alternative embodiment, step 306 is performed on an ongoing bases, either continuously or periodically. In embodiments, the user computer device 60 also determines the number of users of the user computer device 60 using data received from a camera (e.g., 60, 63). Information regarding the facial direction for one or more users, and the number of users, may be stored in a database of the user computer device 60 or fed directly to the content determination module 65 for use in step 307.

At step 307, the user computer device 60 determines a display configuration for a portion of the obstructed content (some or all of the obstructed content) determined at step 305. In embodiments, the user computer device determines a display configuration for the portion of the obstructed content based on the facial direction of one or more user's determined at step 306. In aspects, the user computer device 60 determines a plurality of display configurations, one for each area of the touch screen 61 that is obstructed (e.g., by first and second users). In embodiments, the user computer device 60 determines the display configuration based in part on content display rules received at step 300. For example, the content display rules may indicate that only text-based data should be projected, in which case the display configuration may call for the reproduction and projection of only obstructed text (e.g., rather than obstructed images and text).

In embodiments, the display configuration is a reproduction of the obstructed content determined at step 305. For example, if a user's finger is blocking the letter “V” on a touch screen keyboard, the display configuration for the obstructed content may be a replication of the letter “V” to be projected over the exact location of the letter “V” underlying the user's finger. In embodiments, the display configuration may be configured to adjust for various limitations of the image projector(s) being utilized (e.g., 93, 96). In aspects, the computer device 60 may determine that an amount of obstructed content cannot be projected by the wearable projector device 90 over at least a portion of an obstructed area, and therefore the determined display configuration includes a reformatted version of the underlying obstructed content. For example, if a user's hand is blocking the letter's “F”, “C”, “V”, and “B”, the display configuration may require shrinking the letters “C”, “V”, and “B” to fit over a particular portion of the obstructed content area, while displaying a replication of the letter “F” over the exact location of the underlying letter “F”. This example is depicted in FIG. 4, which is described in more detail below.

Optionally, a plurality of wearable projector devices 90, 91 may be utilized in conjunction with one another (as collaborative devices) to display a desired amount of obstructed content over one or more objects causes the obstructions, in accordance with step 309. In this case, the user computer device 60 configures a plurality of display configurations in accordance with step 307. For example, wearable projector device 90 may be a ring projector with an image projector 93 installed around the circumference of the ring, wherein the image projector 93 has a limited projection range, and may be utilized in conjunction with wearable projector device 91 in the form of smartglasses that have a greater projection range. In such a scenario, the user computer device 60 generates a first display configuration to cause a portion of obstructed content to be projected over an obstructed content area utilizing the ring projector, and generates a second display configuration to cause another portion of the obstructed content to be projected over another obstructed content area utilizing the smartglasses. In embodiments, the user computer device 60 determines that a second user is attempting to view content obscured by the finger of a first user, and adjusts the display configuration such that a projection of a portion of the obstructed content over the first user's finger is from the perspective of the second user.

At step 308, the user computer device 60 sends the display configuration(s) determined at step 307 to at least one wearable projector device 90, 91. In embodiments, the display configuration(s) comprises data defining the manner in which a portion of the obstructed content determined at step 305 is to be projected over one or more areas of the touch screen 61. In aspects, the communication module 67 of the user computer device 60 sends the display configuration to the communication module 95, 98 of one or more wearable projector devices 90, 91.

At step 309, the one or more image projectors 93, 96 of the at least one wearable projector device 90, 91 project obstructed content over the one or more obstructed areas of the touch screen 61 and the object(s) of obstruction (e.g., first and second user's fingers). In embodiments, content projected over a finger of a user by the one or more image projectors 93, 96 changes dynamically based on movement of the finger around the content displayed on the touch screen 61, facial direction alignment of the user, and change in content on the display device. In embodiments, the one or more image projectors 93, 96 project obstructed content over multiple obstructed areas of the touch screen 61 in real time. In aspects, the one or more image projectors 93 and 96 are micro or pico projectors. It should be understood that different micro or pico projectors may be utilized in accordance with the method of FIG. 3. In aspects, the image projector 93, 96 is part of a ring, smartwatch, smartglasses or other smart wearable device that projects obstructed content over one or more obstructed areas of the touch screen 61 (and the objects obstructing the content) in accordance with the display configuration received from the user computer device 60. Advantageously, only obstructed content is projected over the one or more objects obstructing the content, as opposed to conventional projectors that project entire packages of content onto a screen or other object for viewing by a user.

FIG. 4 depicts an exemplary use case for embodiments of the invention. In the scenario of FIG. 4, the user computer device 60 is in the form of a mobile device including the touch screen 61 and the camera 63. Steps of the scenario of FIG. 4 may be performed in the environment illustrated in FIG. 2 and in conjunction with the method of FIG. 3.

As depicted, the touch screen 61 is configured to display content, which is shown in this example as a touch screen keyboard 400 and a chart 401 for “Product F”. A first user indicated at 402 utilizes the wearable projector device 90 in the form of a ring projector. A second user indicated at 403 utilizes the wearable projector device 91 in the form of a ring projector. Initially, the user computer device 60 pairs with both wearable projector devices 90 and 91 (e.g., through Bluetooth) in accordance with step 301 of FIG. 3. The user computer device 60 also displays content (400 and 401) on the touch screen 61 in accordance with step 303 of FIG. 3. The user computer device 60 detects an obstruction of content in multiple areas of the touch screen 61 generally represented at 404-406, utilizing internal proximity sensors 62 (not shown in FIG. 4), in accordance with step 304 of FIG. 3. The user computer device 60 then determines obstructed content in the areas 404, 405 and 406 in accordance with step 305 of FIG. 3.

In the scenario of FIG. 4, the user computer device 60 determines that the hand of the first user 402 is obstructing portions of the touch screen keyboard 400, including the letters “F”, C”, “V” and “B” at areas 404 and 405. The user computer device 60 also determines that the hand of the second user 403 is obstructing portions of the chart 401, including the text “$21,000” at area 406. The user computer device 60 also determines a respective facial direction of each of the first and second users 402 and 403 utilizing the camera 63, in accordance with step 306 of FIG. 3. In this scenario, the user computer device 60 determines that the first user 402 is viewing the touch screen 61 at a first angle represented at A^(o), and that the second user 403 is viewing the touch screen 61 at a second angle represented at B^(o).

The user computer device 60 then determines the display configuration for obscured content in the areas 404 and 405, and the display configuration for the obscured content in the separate area 406, in accordance with step 307 of FIG. 4. In the scenario of FIG. 4, the content display rules stored in the user computer device 60 (received in accordance with step 300 of FIG. 3) limit the content to be displayed to text-based content, such that decorative borders and graphics are not to be projected by wearable projector devices 90 and 91 in communication with the user computer device 60. Thus, the user computer device 60 determines the respective display configurations for obscured text-based content in the areas 404, 405 and 406 of the touch screen 61. Moreover, the user computer device 60 determines the respective display configurations based on the facial directions of the first and second users 402 and 403. The user computer device 60 then sends the display configurations to respective wearable projector devices 90 and 91 in accordance with step 308 of FIG. 3.

Still referencing FIG. 4, the wearable projector device 90 receives the display configuration and projects obstructed content onto the finger of the first user 402 using the image projector 93 (not separately labeled in FIG. 4). In this scenario, the projected content includes the letters “F”, “C”, “V”, and “B”. Additionally, in this scenario, the user computer device 60 determines that a portion of the obstructed content (“V” and “B”) cannot be projected by the wearable projector device 90 over an area 405. Accordingly, the user computer device 60 determined that the display configuration includes letter “C”, “V”, and “B” shrunk and repositioned on an available projector display area represented at 407. Thus, based on the display configuration determined by the user computer device 60, the wearable projector device 90 projects the obstructed content “F”, “C”, “V”, and “B” in a format that enables the user to understand the text-based content that is obstructed by their hand. Similarly, the wearable projector device 91 receives the display configuration and projects obstructed content onto the finger of the second user 403 using the image projector 96 (not separately labeled in FIG. 4). In this scenario, the projected content includes the text “$21,000”, which is obscured by the finger of the second user 403. Thus, it can be understood that a portion of the obstructed content (the text-based content “F”, “C”, “V”, and “B”) is displayed over a finger (finger of first user 402) causing the obstruction of the content, while another portion of obstructed content (the text-based content “$21,000”) is displayed over a finger (finger of second user 403) causing the obstruction of another portion of content.

Advantageously, embodiments of the invention enable the projection of only obstructed content (rather than large amounts of projected content) over the top surface of one or more objects (e.g., user's finger or stylus) obstructing the view of a touch screen. In this way, aspects of the invention enable uninterrupted interaction with the touch screen, in single user or multi-user scenarios.
